SPECIFIGATION forming part of Letters Patent No. 682,915, dated September 1'7, 1901.

Application filed December 1,1900. Serial l lo. 38,668. (No model.) I

To all whom, it may concern;

Be it known that I, FRANK F. CUMMS, a citi zen of ti 1 United States, and a resident of Rutland, in the county of Rutland and State of Vermont, have invented a new and Improved Leather-Working llzfachine, of which the following is a full, clear, and exact description.

' This invention relates particularly to i111 provemcnts in machines for finishing her straps, reins, the; and the object is to provide ainachinc of simple construction oper atingto apply hlacking to the edges of the strap, crease the surface, apply grease to the edges, and punch holes in the strap at sired distances apart.

I will describe a leather-working machine embodying my invention and then point out the novel features in the appended claims.

Reference is to be had to the accompanyin drawings, forming a part of this specification, ih which similar characters ofreference indicate corresponding parts in all the figures.

Figure 1' is aplan view of a machine can bodying my invention. Fig. 2 is a section on the line 2 2 of Fig. 1. Fig. 3 is a section on the line 3 8 of Fig. Fig. at is a section on theline 4 4 of Fig. Fig. 5 is-a section on the line 5 5 of Fig. Fig. (i is a section on the line (3 6 of Fig. Fig.7 is a section on the line 7 7 otrFig. Fig. 8 is a section on Fig. 9 is a general side view of the machine, and Fig. 10 is a dctail showing means for shifting the creasingrollers.

The frame of the machine comprises side pieces 10, within which is a platform 1].. Movable vertically in the lined frame is a frame consisting of side pieces 12, havinginwardlyextended lopilanges 12 ii ranged in the forward portion of the machine and having hearings in the side pieces 10 of the frame is a shaft 14, upon which is mounted a roller 15. Also mounted on the shaft hut adapted for longitudinal adjustment thereof,-

a se sr are brush-holders 16, which have inwardlyextended jaws within which the brush mate rial 17 is arranged. These brush-holders rotate'in a tank 17, designed to. hold liquid blacking, the said tank being supported upon the platform 11, and the tank is held from. lateral movement by having its sidewalls engaged in annular channels 18, formed in the shaft 14. The brush-holders on their outer sides have huh-like portions, which on the outer ends are provided with flanges, and engaging over these huh portions are the side pieces 12 of the vertically-movable frame, so that by adjusting the said side portions 12 toward or from each other the opposite brushes may be adjusted to accommodate them to different widths of straps.

As a means for causing the adjustments of the sides 12 I employ a shaft 19, which has hearings in the sides of the machine-frame and has right and left hand screw-threads engaging-with correspondingly-threaded. openings in the said sides 12. Obviously by To tating the shai'tll) by means of a crank-handle 20 the side portions 12 will he moved toward or from each other, and the required distance may be ascertained by means of a scale 21 on a har22, extended across the machine. During the operation the edge of the strap is held down nponthe roller 15 by means of weights E33, made in the form of lovers, pivoted to the side pieces 12. Rear-ward of the brushes are feed-rollers 2i and 25. The roller 24 has its shaft-hearings in the verticallymovable frame, while the roller 25 has its shaft-bearings in the sides 10 of the machinefranie. Also having hearings in the -vertically-movableirame is a shaft .36, on which creasing-rollers 27 are mounted, which are designed to rotate with the shaft, but are to have a movement longitudinally of the shaft, so as tomove them toward or from each other to adjust them to the width of the strap nnder operationp leneath the creasing-rollers is a bed-roller The cruising-rollers are connected to the shaft :26 by leather and groove, and each creasing-roller is provided with. a huh-like portion, in which is an annular channel 2S {See Fig. 10.) A shift-- rod 30 has a finger 51 at its lower end ongaging in this channel 29, and said rod extends upward through the inwardly-projected flange 13 of the side pieces 12, and pivotally connected to the upper projecting end of the rod 30 is an operating-lever 31, which at its end engaging with the rod is slightly rounded or cam-shaped, so as to engage tightly with the upper surface of the frame-sections 12 when the said leve are turned upward,

The vertically-movable freme is moved upthe ing greasingd'oilers 39.

Ward hymcsn's of posts 32, through which the shaft 19 looly passes, and the lower ends of these posts ore connected to a rod 33,

which extends 'ontwnrd through openings in the side pieces 10 below the platformli, and

ennncctinp; with. ihisrod 33in a. lever 3i, consisting nit" twonideginenshers connected at the ends, the said side members being mounted to swing on as red Bfit cdnuected to the main fr-nine rest-nerd of the rod '33. Suspended irorn the front end of the lever'3i'is weight 36, and. fronrthe other end of said lever- 34 a rod 3'7 extends downward to n connection with n trendle 38. By forcing the trendle downwnrd the frnmecomprieing the side pieces 12 will he moved npwnrd;-'so that a. strap may be readily inserted between the feed-rollers.

Bearward of the creasing-rollers and adapt ed for engagement with oppositesides of the strap under operation arehorizontally-rotat- Thcso greasing-roll- (are are mounted on shafts 40, having bearings in the frame 12, end on the lower ends of these shafts ere; pinions 4.1, which meshwith crown-wheels 42', attached to a shaft 43, hev in? hearings in the frame members 10.

:1 the side portions 12 of the verticallymovablc frame are openings'i i, which form cups for holding grease. These cups at the lower end are provided with an opening through which the grease may pasd'to the rollers 39. The grease is forced downward by means of a. plunger 45 operating in said cups and pressed upon by springs 46, the upper ends of which engage with a. cross-bar 4:7.

It will be seen that the pinions 41' are made quite wide, so that during the'verticcl movements of the transom said pinions will not be disengaged from the crown-wheel's. Recrward of the grossing-rollers is a punch-carrying bar 48, having its ends engsginginguides 29, attached to the inner sides of the side pieces 10, end extended, downward from the ends of the punch-carrying bar 48 are rods 50, which pass freely through openings in the platform 11, end arrangedbetwecn the upper side of this platform ltend thc .iln'der sideof 1 the hnr 48 jare cushion springs '51, these springs 51 being coiled around the said'rods 50. The center of the bar 4'8 is provided with an opening in which a punch'52 may iodin sorted. Of course a punch of any desired size maybe employed.

ywith the carryinwbar I employs. tappot do y. i H

its n monies for forcing the punch downtime;

when of the sleeve 53, so that by adjusting the sleeve v 53 lonnitudinnliy of the shnft 55, on which itis mounted, the said ieppet-fing'ers may be brought into position tocause one or more of s'sid fingers to e ngngo with the punch during the rotation of the sleeve-ihat is, by moving the sleeve 53 to its extreme position toward it ii'y-wheel 56 on the shaft 55 the widest tnppetfinger only will engage to operate the punch. Therefore the punch will be operated but once at each complete rotation of the shaft 55. Should it be desired to punch two holes closer together, the sleeve 53 is to he moved, so that not only the longer tnppet-finger will engage with the pnnch, l: ut the next longer topmost finger will also engsge with the pnnch This will cause two movements of the punch during one rotation of the shnft. Obviously by moving the sleeve. to its extreme position away frond the fly-wheel 56 nil oi the tsppets will he brought into position to operate the punch.

The sleeve 53 is moved in one direction by menace of a nut 57 engaging with a screwthre'n'd on the shaft 55 and shutting at its end against one end or" the sleeve 53. The sleeve is moved in the opposite direction when the nut is released or moved toward the fly-wheel hymesnn of as spring 58, surrounding the shaft and engaging at one end with the end of said sleeve and at theother end with one.

or the arms. 59, connected to the shaft 55.

These arms 59 are for the purpose of raising or lowering the shaft 55 to move the punch into or out of operative position. These arms ,59 are connected to n rocinshaft 60,.having hearings in the frame members 10, and the sleoro 53, and its lower end is designed to en- Y gage'with a stop 63 on the platform 11 when the arms or frame is moved to-bring the ,tnppet device to operative position, as indi- 4 carted in Fig. 2. Below the punch and inclined downward and rearward is a bed-p1nte 64, down which the niateriaLQpnnched-wt will dischhrge'. On the-outer end of the shaft 65, on which the roller 28 is noinnted, is a. drivewheel 66, that may be opennt 'd either by a. enitnhly-driven hnnd or ma b2 manually op ,ereted joy a'crankdiendle 61. i On' this end of r heel 69, attac ed ,to'the shaft 5 r on she 0 v pinionjm meshing withn pinion/When the EfihflgflififiIfil'idflriSdOll this niinftgofisn pinion J2; engaging with an'idlertfn, whichn eshes oller 25f end this pinion gear-wheel 8,; which meshes pposite end oil/the shaftfio is a a U i i fimthapimon- 74 on thehhnft ofthe feed t es wit I nni dinrifi, engngingwithnpinion 76 on the 1 Jim t, h i n were shcit r n lower feed-roller meshes with a pinion 78 on the shaft of the upper feed-roller. It will be seen that these several pinions are arranged between one of the side members 12 of the vertically-movable frame and one of the side members 10 of the fixed frame. The pinion 72 also meshes with a pinion 79 on the shaft 43 for rotating the crown-wheels 42, and consequentlyoperatiiigthegreasing-rollers. The frame or arms 59 when n'aoted to tliei'rdowiiward position are prevented from jar by means of cushion-springs'S which engage at the lower end with the platform 11 and at their upper end with tubes or sleeves 81, against the upper ends of which the'said arms 59 may strike. By the system of gearing it will be seen that the several rollers and brush-carrying devices will be rotated together.

In operation the vertically-movable frame is to be elevated by the means described and the end of the strap inserted between the feed-rollers 24 and 25. Then upon rotating the drive-shaft the several parts will be operated while the strap is moving through, so that blacking will be first applied to the edges of the strap, then the creases near the edges will be formed, and then the greasing-rollers will apply the grease to the edges, which will give the desired polish. If it is desired to punch holes through the strap at its end first passed through the machine, the punching device of course is to be brought into operation. When, however, it is not desired to punch holes, the shaft 55, carrying the tappet device, is to be elevated.

Having thus described my invention, I claim as new and desire to secure by Letters Patent-- said frame, circular brushes mounted to rotate through said tankand adjustable toward and from each other, and fecd-rollers, substantially as specified.
